When there is
no more mental pain or grief, Nirvana becomes perceptible, comprehensible,
inviting and attractive. It is the complete and final cessation
of greed or craving, hatred and ignorance, and therefore the cessation
of rebirth and of the continuity of life. Dharma-kaya, Prajna and,
consequently, freedom manifest themselves to their fullest. Nirvana
cannot be expressed through words; it has to be experienced.
